I believe lhuchison is an SWL, not a amateur. So he should have none of those issues. But two issues he may have...
Is the house Protective Multiple Earthed?? If so the whole house could become live if he uses any earth, especially the house plumbing. If there is a problem in his or any other house or the transformer that is part of that system.
Secondly it can introduce QRM into the system.
If anyone is unfamiliar with the Q code.
QRM = Man made interference, such as from LED lights, fish tank pumps, street lights, boiler systems, switch mode power supplies & the dozens of other sources.
QRN = Natural interference, that is the natural background noise from the solar system.
